mwiegand 4619a91f45 fix(l4d2-web): file tree layout — wrap children to next line, align names Two CSS fixes that together turn the rendered file tree from 'everything on one line' into an actual tree: - .file-tree-children: flex-basis: 100% so an expanded folder's children wrap to the next line of the parent <li> flex container instead of flowing inline next to the toggle button. - .file-tree-row-file: padding-left = chevron width, so file rows align visually with sibling folder names (folder names are offset by their chevron; files have no chevron, so without padding they'd start at the chevron column instead of the name column). Chevron itself pinned to width: 1ch so rotated/un-rotated states have identical layout.		2026-05-08 20:44:41 +02:00

README.md

l4d2-web-app

Flask web app for managing L4D2 servers through user-private blueprints.

Key v1 behaviors

Local username/password login; no public signup
Admin-managed overlay catalog
Private blueprints per user
Server creation from blueprints (live-linked; no per-server blueprint overrides)
Async job model with persisted command logs in job_logs
Desired vs actual state model
Live logs for jobs and servers via SSE endpoints
Host operations go through l4d2ctl via a local host command runner, not direct l4d2host imports

Frontend constraints

Server-rendered templates (Jinja)
Vendored HTMX (static/vendor/htmx.min.js)
Custom CSS only
Tokenized, consistent link and accent colors

Development

python3 -m venv .venv
.venv/bin/pip install -e .
.venv/bin/pytest tests -q

Configuration

The web app reads these settings from the environment:

DATABASE_URL: SQLAlchemy database URL, for example sqlite:////var/lib/left4me/left4me.db.
SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.
JOB_WORKER_THREADS: number of background job worker threads.

In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.

Admin Bootstrap

Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:

LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
